No DTE function in the SX. I mean, I knew I wasn't getting it, but my 13-year-old base-model Falcon has it?!
I thought the Ultragauge would fix me up, and it has somewhat (arrived today) but without a fuel level sensor it's just not the same... I've been reading CAN-bus protocol documentation with the idle thought that perhaps with some old 9s12 dev kits I have lying around I could write some code to inject additional data frames for the Ultra-gauge to display, but I already have enough unfinished projects :}
